COLORADO.

FURNACE.

SPECIFICATION forming part of Letters Patent No. 518,493, dated April17, 1894.

Application filed April 6,1893. Renewed March 6, 1894. Serial No.502,593. (No model.)

To all whom it may concern:

Beit known that we, AUGUSTUS L. ENGEL- BAGH and SIDNEY E. BRETHERTON, ofLeadville, in the county of Lake and State of Golorado, have inventedcertain new and useful Improvements in Furnaces, of which the followingis a full, clear, and exact description.

The invention relates to furnaces such as shown in our United StatesPatent No. 496,250, dated April 25, 1893.

The object of the invention is to provide certain new and usefulimprovements in furnaces, whereby the molten products are prevented, toa great extent, from incrusting in the settler, and also whereby thesettler may be readily moved to or from the heater if incrustationshould possibly take place.

The invention consists of certain parts and details, and combinations ofthe same, as will be hereinafter described and then pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a sectional side elevation ofthe improvement on the line1--1 Fig. 2 5 and Fig. 2 is a transverse section of the same on the line2-2 of Fig. l.`

The improved furnace is provided with a heater built in suitablebrickwork A, in which is arranged a fire-box B, containing a grate C, onwhich the fuel is burned in the usual manner. The fire-box B connectswith a heating and combustion chamber D, through which pass the airpipes E, connected with the smelting furnace, as more fully shown anddescribed in the application above referred to.

X is an open rectangular plate or frame around the upper edge of thechamber G and provided on its upper sides with lugs or projections X onwhich rest the pipes E as clearly shown in the drawings. The rear end ofthe heating chamber D is connected with a chimney F, to carry 0E theproducts of combustion.

In the brickwork A is arranged a recess G,

into which is adapted to be moved a settler H, provided with an inletspout I, through which the molten metal from the smelting furnace isdischarged into the settler, and the latter is also provided with amatte discharge spout .I and one or more slag discharge spouts K.

As illustrated in the drawings, the settler H for the molten ore, ispreferablyin the form of a cast iron box lined with fire brick asindicated in the drawings, and this box is set on a frame L, andfastened thereto by bolts P, pivoted to the uprights of the frame andswinging into the slotted lugs P projecting from the cast iron box atthe corners thereof, or other suitable means. The frame L is providedwith wheels N, adapted to run on track rails O, leading into the bottomof the recess G so as to permit of conveniently running the settler inor out of the recess G. The settler is preferably made of suchdimensions as to completely fill the recess G to prevent loss of heat.It will be seen that the heat generated by the burning fuel on the grateC keeps the molten metal in the settler H suciently hot to prevent asmuch as possible, any incrustation, and the heat of the molten metal runthrough the spout I into the settler H is utilized for heating the iiuesE through which passes the air, in addition to the heat generated by theburning fuel on the grate C and passing through the chamber D. In casethe incrustation does take place in the settler H, then the latter canbe readily run out of the recess G and a new settler of likeconstruction be run into the recess, without any loss of time, so thatthe process of smelting ores as described in the above mentionedapplication, is not interrupted or interfered with to any great extent.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent-- l. A furnace comprising the ire box, acombustion chamber leading therefrom to the chimney, air pipes Ecrossing the combustion chamber, a recess opening upwardly into theCombustion chamber under the said air pipes With pivoted bolts to swinginto the slots of and a Wheeled settler movable into and out said lugs,substantially as set forth.

of said recess, substantially as set forth. AUGUSTUS L ENGELBACH 2. Thesettler formed of a east iron box 5 lined with flre clay and provided onits outer SIDNEY E' BRETHERTON side at its corners with slotted lugs andthe Witnesses: Wheeled frame L into which the settler fits FRANK SHAW,and provided on its vertical corner uprights J. W. SATTEN.
